PdZn/TiO2 catalysts were synthesized by sol-gel method using a template Pluronic F127. PdZn nanoparticles were prepared by ethylene glycol reduction of ZnCl2 and Pd(CH3COO)2 in the presence of stabilizer and introduced into the matrix by addition into TiO2 sol, followed by different activation procedure. The structure, particles size and chemical composition of nanoparticles and catalysts were characterized by transmission electron microscopy, X-ray photoelectron spectroscopy, X-ray fluorescence spectroscopy, energy dispersive spectroscopy. The prepared catalysts have been tested in the selective hydrogenation of 2-methyl-3-butyn-2-ol, and the results have been compared with catalysts prepared by conventional impregnation. The results indicate that bimetallic PdZn nanoparticles-based catalysts show higher selectivity than corresponding monometallic Pd/TiO2. Embedded on titania bimetallic nanoparticles stabilized with polyvinylpyrrolidone exhibit good activity (1.1 to 1.8 molMBY/molPd/s-1) and high selectivity to 2-methyl-3-buten-2-ol (81.5-88.9 % at 95 % conversion). The influence of the nature of the stabilizer, the stabilizer/metal molar ratio and activation conditions on the catalytic behavior of the samples was analyzed. It is shown that the particle size does not significantly affect the catalytic properties in the range of 4.4 to 6.5 nm. The nature and amount of stabilizer seems to be crucial to prepare efficient catalyst.
